In addition to the estimates that can be downloaded directly from this website, historical OES estimates are available upon request through the contact information above. Historical OES estimates consist of the 1988 to 1995 national occupational employment and wage data by industry, for most industries at the 2- and 3-digit Standard Industrial Classification (SIC) levels. Estimates for 1988 - 1995 contain only employment data. Between 1988 and 1995 covered industries were surveyed once in a three-year cycle. The OES program now surveys all covered industries each year.

Note: 1996 estimates are not available.

OES State Employment and Wage Estimates

Occupational Employment Statistics estimates, by occupation and by industry, for individual states are available from the states' Labor Market Information (LMI) or Research, Analysis, and Statistics offices which are part of their State Employment Security Agencies (SESAs). Availability, format and medium of the data varies by state. To obtain OES estimates for a particular state, please contact the appropriate office on the State Contact List.

Northern American Industrial Classification System

In order to classify occupations by industry, the OES survey uses the North American Industry Classification System (NAICS). See the NAICS Division Structure for more information about the NAICS system.
